Noise eliminating products. Remove unwanted background noise and interference leaving only the speech. Clear communications, listen stress free. Dsp noise cancellation solutions.

This project was intended to accompany the stealth antenna project. Author want to see how effective a noise canceller could be in reducing the background noise floor when attic / stealth antennas are being used.

Article on Phase-cancellation of noise on 2m band

Amateur radio enthusiast Jean-Paul Suijs discusses combating manmade noise (QRM) in radio signals using AI. Detailing experiments with phase-shifting techniques and the self-learning nature of AI, he explores AI-based audio processing apps for real-time noise cancellation during radio contests, demonstrating results on both medium wave and shortwave bands.

Noise-canceling electret condenser microphones (ECMs) are ideal for compact, battery-powered devices due to their small size, low power consumption, and high sensitivity. These microphones, used in conjunction with active noise cancellation circuitry, significantly reduce ambient noise, creating a more peaceful listening experience by combining and processing signals from multiple microphones.
